I SIDE-FILLING STOP-MOTION FOE LOOMS.

Specification of Letters Patent.

Iatented March 16, 1909.

Application filed October 30, 1908. Serial No. 460,217.

To all whom it may concern:

Be it known that I, OnILDs PAnTLoW, a citizen of the United States,residing at Rockhill, in the county of Yorkand State of South Carolina,have invented certain new and use ful Improvements in Side-FillingStop-Motions for Looms, of which the following is a specification.

My invention relates to a stop motion for looms, to stop the loom onthefailure of filling, and myinvention particularly relates toimprovements in the filling stop motion of a loom, ordinarily termed aside filling stop motion.

Side filling stop motions are intended to stop the loom every secondpick, in case there is no filling, but not to stop the loom in case thefilling, which runs from the shuttle to the selvage of the fabric, islaid before the reed, or the grate, which takes the place of the reed.The filling fork of the side stop motion feels against the weft orfilling, and causes a hook to be raised, to prevent it from beingengaged by a lever which operates the stop motion. In case of breakageor failure offilling, atthe next pick of the shuttle to the oppositeside of the loom, there will be no filling to hold the filling fork, andit will pass throu h the dents of the reed, or the grate, and will notcause the hook to be raised, but allow it to be engaged by a lever, andoperate the slide on which the fork is carried, to stop the loom. If thefilling fork or feeler wire is bent out of shape, so that it willnot'pass through the reed, or grate, or if any loose filling threads orwool fiber, or dust on the lay beam, clog the reed or grate, and preventthe filling fork or feeler from passing through the reed or grate,thenthe fork or feeler will be moved the same as if there were fillingfrom the shuttle to move it, and the loom will not be stopped on thefailure of the filling.

The object of my invention is to improve upon the construction of theordinary filling fork or feeler, and to cause it to be operated to stopthe loom, in case of the failure of filling, and when for any reason thefilling fork or feeler does not pass through the reed or grate, as itshould.

My invention consists in certain novel features of construction of myimprovements as will be hereinafter fully described.

In my improvements as herein shown, I

provide the filling fork or feeler, with a double hook, one hook abovethe regular hook. The second or extra hook will be caught by a secondlever, to stop the loom when the active shuttle isqon the opposite sideof the loom from the filling stop motion.

I have only shown in the drawings a detached portion of aloom, and aside filling stop motion of the usual construction, with my improvementscombined therewith.

Referring to the drawing :-Figure 1 is a vertical cross section througha detached portion of a loom, showing a side filling stop motion with myimprovements combined therewith. Fig. 2 corresponds to Fig. 1, but showssome of the parts in a different position, and, Fig. 3 is a plan view ofthe filling stop motion slide, looking in the direction of arrow a, Figi1 7 in the accompanying drawing, 1 is aportion of the loom side or endframe, 2 the breast beam, having the side filling stopmotion mountedthereon, and consisting of a guide plate 3, the stop motion slide 4,having the filling fork 5 loosely mounted on a stud 6 in the rearwardlyextending end of the slide 4. The forwardly extendingportion 5 of wardlyextending hook 5 which is adapted to be engaged by the head 7 on theupwardly extending end of a cam lever 7, on the for ward movement ofsaid lever, in the caseof the failure of filling, to move the slide 4,and operate a lever 8 pivotally mounted on ya stud 9, see Fig. 3, on thebreast beam, to stop the loom, in the usual way. The rear end of thefilling fork 5 is adapted to pass through the reed or grate 13, onthe'lay 16,'in case of failure of filling, on the forward stroke of thelay 16. .The cam lever 7 has its hub 75'" loosely mounted on a stud 10,and has its the filling fork 5 is provided with a downother arm extendrearwardly and downwardly in the path of, and to be operated, at everyother pick, by a cam 11 secured upon the bottom shaft 12. All of theabove mentioned parts, except the fillingfork 5, may be of the usual andWell known construction.

I will now describe my improvements. The forwardly extending end 5 ofthe filling fork 5 has a second hook 5 thereon in this instance locatedon the upper side of the end 5, and directly above the lower hook 5".The upper hook 5 is adapted to be moved into the path of, and be engagedby the end or extension 14 of an upwardly extending lever 14. The hub 14of the lever 14 is in side of the loom opposite from the filling forkmechanism.

From the above description in connection withthe'drawings, the operationof my improvements will be readily understood by those skilled in theart.

In the normal operation of the loom, the filling in front of the reed orgrate 13 will engage the filling fork 5 on the forward beat of the lay,at every other pick, and hold the hook end of said fork out of the pathof engagenient with the end 7 on the cam lever 7, and the end 14 on thecam lever 14 will not be in position to engage said fork, as shown bybroken lines in Fig. 1, but on the failure of filling, the filling fork5 will pass through the reed or grate 13, and allow the hook end 5 todrop down, so that the hook .5 will be in the pathof the extension 7 onthe lever 7, as shown by full lines in Fig. 1, and be engaged by saidextension, to cause the slide 4 to move forward and operate the lever8,.and sto the loom in the usual way.

In case the filling fork 5 gets bent, or the reed or grate 13 isclogged, then the filling fork is prevented from passing through thereed or grate on the failure of filling, so that 011 the forward beat ofthe lay, the filling fork 5 is raised at every pick, as shown in Fig. 2,and the upper hook 5 thereon will extend in the path of, and be engagedby the extension 14 on the cam lever 14, when the shuttle is on theopposite side of the loom from the filling fork mechanism. Through themove.- ment of said cam lever 14, the slide 4 will be moved forward, andthe lever 8 operated to stop the loom, in the same manner describedabove in connection with the failure of filling.

The operator may then straighten the filling fork, or remove the dust orother material which has clogged the reed or grate 13.

The advantages of my improvements will be readily appreciated by thoseskilled in the art. They are of very simple construction, and can bereadily applied to and used in connection with the ordinary side fillingstop motions, and if for any reason the filling fork is prevented frompassing through the reed or grate, when the shuttle is on the oppositeside of the loom from the filling fork mechanism, the loom willbestopped.

It will be understood that the ldetails of construction of myimprovements may be varied if desired.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is 1. In a loom, the combination with a sidefilling stop motion, of mechanism connected therewith to automaticallystop the loom when the shuttle is on the opposite side of the loom fromthe filling stop motion, and the filling fork of said motion isprevented from passing through the reed or grate.

2. In a loom, a side filling stop motion having a slide, and a forkthereon with a double, y

or two hooks, for the purpose stated.

'3. In a loom, a side filling stop motion having a slide, and a forkthereon with a double,

or two hooks, one of said hooks, through operating mechanism, adapted tomove said slide to stop the loom when the shuttle is on the oppositesideof the loom from the filling stop motion;

4. A loom side filling stop motion having a pivotally mounted fork, andmechanism 00- operating. therewith to stop the loom when the fork is nottilted, and mechanism cooperating therewith to automatically stop-theloom when the fork is tilted, on alternate picks.
